スペースデブリ捕獲に向けた金属製銛撃ち込みに関する数値シミュレーション

抄録

Numerical models for investigating penetration behavior of a metal anchor have been developed and its applicability was demonstrated. Two types of FEM mesh, triangular mesh and quadrilateral mesh were employed and some numerical simulation were carried out. These results were compared with the experimental results. It is observed from the results that the penetration behavior can be simulated properly using the triangular mesh. The effectiveness of the Johnson -Cook model with triangular mesh was demonstrated through the comparison.
